Remember when the Autodesk Labs team worked on Project Twitch - the ability to run design applications on remote servers. You can see one of the fruits of our labor on the AutoCAD LT 2013 page.
You can try AutoCAD LT 2013 without downloading and installing it. You get to play with it for free for 30 days. How cool is that? You run it on servers in the Autodesk 360 world.
There is a 540K (K not MB or GB) download of a Citrix player, but that is a far cry from the 1.37GB download of an installer for a local copy of AutoCAD LT 2013.
Virtualization is alive in the Lab.
